🔧 Camry - Fuel Pump Replacement

The fuel pump on your Camry Hybrid is inside the fuel tank as a pump/module assembly. Replacement is usually done from inside the car under the rear seat, so you don’t have to drop the tank.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

Assumption: In-tank fuel pump/module accessed under rear seat.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Relieve fuel pressure

• Remove the fuel pump/fuel system fuse or relay from the under-hood fuse box using needle-nose pliers.
• Start the car and let it run until it stalls, then crank for 2-3 seconds once more.
• Turn the car OFF and remove the key/fob from the vehicle.
• This reduces spray when lines open.

Step 2: Remove the rear seat cushion

• At the front edge of the rear seat bottom, pull up firmly to release the clips (use a trim removal tool set if needed).
• Lift the cushion out of the car and set it aside.

Step 3: Open the fuel pump access cover

• Locate the round/oval access panel on the floor under the seat.
• Remove the cover fasteners using a 10mm socket.
• Lift the cover and move any butyl/foam seal aside carefully using a small flathead screwdriver.

Step 4: Disconnect electrical connector(s) and fuel line(s)

• Unplug the fuel pump electrical connector by releasing the tab with a small flathead screwdriver (gentle—tabs break easily).
• Place shop towels around the fuel line connection.
• Disconnect the fuel line using a fuel line disconnect tool set if required by your fitting style.
• Cap/cover the open line ends with clean shop towels to keep dirt out.

Step 5: Remove the lock ring / retaining hardware

• Clean dirt off the top of the module and tank area using shop towels so debris doesn’t fall into the tank.
• If equipped with a lock ring: loosen it using a Toyota fuel pump lock ring wrench (specialty).
• If you don’t have the wrench: use a brass punch and small hammer to tap the ring counterclockwise. (Brass helps reduce spark risk.)

Step 6: Lift out the fuel pump/module

• Carefully lift the module straight up while guiding the float arm (fuel level sender) out without bending it.
• Let fuel drip into a container for fuel-safe draining before moving the module away from the opening.

Step 7: Replace the tank seal O-ring

• Remove the old seal/O-ring from the tank opening using a trim removal tool set.
• Install the new O-ring clean and flat (no twists). Do not reuse the old seal.

Step 8: Install the new fuel pump/module

• Lower the new module into the tank, guiding the float arm in smoothly.
• Align the module marks/tabs with the tank indexing marks.
• Install and tighten the lock ring with the Toyota fuel pump lock ring wrench (specialty).
• Torque: Tighten the lock ring/retainer to Toyota specification for your module style (often provided with the part). If your setup uses small nuts/bolts, tighten evenly in a crisscross pattern with a torque wrench (inch-pound).

Step 9: Reconnect fuel line(s) and electrical connector(s)

• Reconnect the fuel line until it clicks/locks; gently pull back to confirm it’s latched.
• Reconnect the electrical connector until it clicks.
• Wipe any spilled fuel with shop towels and let vapors clear.

Step 10: Reinstall access cover and rear seat

• Reinstall the access cover and fasteners using a 10mm socket.
• Reinstall the rear seat cushion: set it in place and push down firmly to re-engage the clips.

Step 11: Restore power and prime the system

• Reinstall the fuel pump/fuel system fuse/relay using needle-nose pliers.
• Reconnect the 12V battery negative terminal using a 10mm socket.
• Turn the ignition ON (READY) for 5 seconds, OFF for 5 seconds; repeat 2-3 times to prime.

✅ After Repair

• Start the car and let it idle while checking the access area for any fuel smell or dampness.
• Check for leaks at the fuel line connection and around the module seal.
• Test drive 5-10 minutes, then recheck for any fuel odor and recheck for leaks.
• If a check engine light appears, scan for codes (often a loose connection or EVAP leak from sealing issues).
